Old Navy Outlet

I am writing to express my disappointment regarding a particularly unpleasant experience I had with a cashier during my recent visit to your store in sawgrass mills mall over the holiday season. As I approached the young lady on december 26, I was met with an unfriendly demeanor and a lack of basic courtesy when I asked a simple question about picking up my online order  (which instructions in the email said to follow the sign in store and approach the register next to the sign which it was her register and why i asked ) she responded with a dismissive tone to "make the line". I asked her if she was sure because the instructions in the email said to go to the register and ask and,  she cut me off and said " you still have to make the regular line" As a made the long line i noticed that another customer approached her with same question of  online order and she attended to him right away ( unlike me he didnt not have to make the long line) . I'm not sure why it was treated so indifferent when I was extremly polite. This type of customer service is unacceptable, especially during a time when kindness and patience should be prioritized. I dont recall the young lady's name because I left the store feeling so confused about her actions towards me but I do remember she was on the last register and she had long braids with an accent of red/burgundy. The second young lady that attended me after making the line was really polite and apologize for the incident which i appreciate but it defeated the whole purpose of online ordering.   I hope my feedback helps to improve the experience for future customers, as no one deserves to be treated so rudely while shopping during a season meant for joy and celebration.
